Quite a lot of the character names are Shout Outs to characters in the original series, as well as others:
John Young is a combination of original series character John, played by Nicholas Young.
Jedikiah (a name reused from the original) has the last name Price, referring to original series creator Roger Price.
And of course, John's father's real name is Roger Price.
Cara's name is reminiscient of original series Carol.
A possible Shout-Out to Roman times is the name "The Citadel" for Ultra's "research center". At least one reference indicates that Roman prisons were called citadels.
In the opening scenes of the pilot, we see Stephen has a London poster on the wall of his room, a nod to the original series' British origin.
